资 源 简 介

以单片机、烟雾传感器、温度传感器等器件为核心,设计并制作了一款家用智能火灾报警器。当环境中烟雾浓度或温度超过设定的报警值时,烟雾传感器把被测量转换为电量输入模数转换器,模数转换器将检测到的电信号转换为单片机可以识别的数字信号,单片机根据接收到的烟雾信号和温度信号做出判断,驱动声光报警电路和显示器件工作,发出声光报警信号并显示当前的烟雾值和温度值,由此实现对发生的火灾及时报警。与文献结果相比,该报警器体积小,成本低,便捷可靠,适合家庭使用。

Based on MCU,smoke sensor,temperature sensor and other devices,a home intelligent fire alarm is designed and manufactured.When the smoke concentration or temperature in the environment exceeds the set alarm value,the smoke sensor converts the measured value into the electric quantity and input it into analog-to-digital converter,the analog-to-digital converter converts the detected electric signal into the digital signal that can be recognized by the single-chip microcomputer,then the single-chip microcomputer makes a judgment according to the received smoke signal and temperature signal,drives the sound light alarm circuit and display device to work,and sends out the sound light alarm,so as to realize the fire alarm in time.Compared with the results of literature,the alarm is small in size,low in cost,convenient and reliable,and suitable for home use.
